I ave a German Trumpet that has the stainless valves from Bauerfeind 8 the best valves I ever had) , but
I didn't figured out until recently that Bauerfeind makes also monel valves
Besides they also makes different weight and stroke pistons.
Another surprising feature is that they make two part casings, like old Bachs.
Quite a lot to chooseĦĦĦ.-
A question to repairers, How do you think that stainless could be repaired.?
